To address increasing requirements for greater brake output and improved NVH (noise, vibration, and harshness) performance, TRW has developed two calipers that fit within the environment of a conventional brake caliper package while providing greater torque output. Previously, the typical approach to achieve greater torque output was to increase rotor and wheel size, which increased cost and weight.

Both of these designs incorporate TRW's innovative pinned-abutment pad guiding approach to improve NVH performance. In comparison to competitive products, these designs also offer increased brake friction pad area which improves durability performance.

TRW's FBC/FBA Caliper Features:

• Single or twin piston configurations
• Modular construction, incorporating full aluminum or composite (aluminum pot plus cast iron or forged steel bridge) housings
• Applications from passenger cars to light trucks
• Piston size – 57 and 60mm (others under consideration)
• Housing guiding system sealed for life

TRW's FB-4OP Caliper Features:

• 4-piston configurations (2 opposing 2)
• Composite and full aluminum designs
• Applications from passenger cars to light trucks

Piston sizes – T34, T43 mm (others under consideration)
